Specification of Letters Patent.

Patented June 30, 1908.

Application filed May 15, 1907. Serial No. 373,823.

for use as an outdoor lamp; second, to pro-- vide an improved gas lamp having inverted burners in which the burners and the burner valves are effectively protected, and, atthe same time, one in which they are easily accessible for purposes of adjustment and the like; and third, to provide an improved gas lamp having inverted burners in which the parts above the burners are so constructed andarranged as to prevent their becoming heated to an undue extent.

Further objects, and objects relating to details of construction, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims. I

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which,

Figure 1 is a vertical central section through my improved gas lamp, thegas delivery pipe, the casing of the valve therefor,

and the burners being shown in full lines Fig. 2 is an enlarged horizontal section taken on a line corresponding to line 2-2 of F i 1 Fig.3 is an enlarged horizontal section ta en on a line corresponding to line 3'3 of Fig. 1; Fig. 4 is an enlarged detail elevation of the globe-supporting band; Fig. 5 is an enlarged plan View of the mantle holder removed from the lamp with a part of the mantles removed;

6 is an enlarged detail section taken on a line corresponding to line 66 of Fig. 5; Fig. 7 is an enlarged detail section taken on a line corresponding to line 7'7 of Fig. 5; Fig. 8 is a detail view showing a modified form of the chimney casing; Fig. 9 is an enlarged, transverse section through the valve casing 6, taken on a line corresponding to the. broken line 99 of Fig. 1; Fig. 10 is a detail longitudinal section through the valve taken on a line corresponding to the line 1010 of Fig. 9; and Fig. 11 is an enlarged detail section of the burner showing the structural details of the gas delivery nozzle.

In the drawing, similar numerals of refer-.

ence refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the gas delivery pipe is preferably made up of the supply pipe 1 having a T-coupling on its lower end to which the pipe sections 3 and 4 are connected, the section 4 being a dummy.

At the lower end of the gas delivery pipe is a valve casing't), which controls the delivery of the gas to the gas delivery ring 5. The

valve casing 6 is preferably arranged to project outwardlyand downwardly, as clearly appears from the drawing.

The burners, 7 ,--.of which I preferably provide a plurality as illustrated,-are connected to the gas delivery ring 5. The burners are preferably of the Bunsen type, being provided with suitable burner tips, as 8,.and valves, as 8. The burners are arranged through the outwardly-projecting flange 10 at the lower end of the chimney 9 with their tips below and their valves above the same, preferably in an inclined position, as illustrated, the upper ends of the burners being directed outwardly.

The chimney flange is preferably turned 11 wardly at 11, and is also preferably pro vided with an annular downwardly-projecting flange 12, within which the burnertips are arranged.

A chimney casing 13, having an outwardlyprojecti-ng flange 14 at its lower end, is arranged about the chimney in a spaced rela tion thereto to form a conduit or passage for air, the chimney casing being open at its upper end, which is preferably arranged so that it is somewhat below the uppen end of the chimney. The chimney casing preferably rests on the upturned portion 11 of thechimncy flange and is provided with openings 14 through which the burners are arranged. The chimney and chimney casing are preferably connected by means of suitable bolts as 15, the chimney casing being connected to the pipe sections 3 and 4 by means of suitable clips as 15. The openings 14: in the chimney casing flange are preferably of such size as to permit the flow of air into the chimney bro casing about the same, but a satisfactory structure may be produced by providing the air inlet openings for the casing at its edge, as shown in the modified construction of Fig. 8.

An outer casing .16, having an outwardly )ortin band 23 which is ada ted when in its closed positidn, to close against the under side of the flange 17 on the outer casing. The globe-supporting band is adjustably supported, being preferably hinged, so that it may be swung'down out of the way when it is desired to secure access to the burners, mantles, or the like, it being shown in its open position by the dotted lines in Fig; 1.

The hinge preferably consists of the outwardly and downwardly-projecting hinge member 27 secured to the valve-casing 6 the outwardly-projecting hinge member 28 on the globe-supporting band, and the pintle 29. By this connection, when the globe-supporting band is open, it swings down and away from the burners, so as to afford free access thereto. The globe-supporting band is preferably held in its closed position by the pin 30, which is adapted to engage over a suitable stop 31 carried by the chimney flange. The globesupporting band is provided with a double series of perforationsas 25 and 26. These series of perforations are separated by the inwardly-projccting flange 24, which is adapted, when the globe-supporting band is in its closed position, to co-act with the flange on the chimney in separating the chamber formed by the globe from the chamber above.

the flange. i/Vhen the globe-supporting band is in its closed position, the air passes through the openings 26 therein to the burners, and through the openings 25 to the air ports of the burners, and to the chimney casing, and also there is, under ordinary circumstances, a current of air passing out of.

the top of the outer casing.

In operation, a current of air is created in the chimney casing, and the air, being drawn in at the bottom thereof, about the burner mixing tubes, very effectively cools the same. In the preferred construction shown in Figs. 1 and 2, the air is effectively directed so that it flows over the entire up er end of the In the modifie construction toa less degree.

Another advantage of the chimney casing is that it forms the air chamber between the chimney and the gas delivery pipe and burner valves, so that the heat radiated from the chimney is largely carried off bythe chimney casing. The. outer casing, being open at its upper end, also creates anupward draft of air, so that it assists in the cooling of the parts, which, it will be readily understood, is a very great advantage.

I The mantle supporting plate .32 is preferably su ported by a rod 33 adapted to be verticaliy and revolubly adjusted in the lug 34 through which it is arranged. A suitable button, as 34", is provided on the opposite end of the flange 12 for holding the plate-like mantle holder in its adjusted position. The mantle holder 32 is adapted to fit the flange 12 on the chimney, as clearly appears from,

Fig. 2. The mantle support is provided with openings 35 adapted to receive the mantle holder rings 38. The mantle holder is provided with upwardly-projecting flanges36 about the openings 35, and these flanges arenotched, as at 37, to receive the arms 39 on the mantle holders 38. The mantles with the mantle holding rings thereon are dropped through the plate from above the same, the

arms or lugs 39' being dropped into the notches 37. This effectively olds the mantles in their proper position, centering them and locating the lugs so that the armsor I lugs of one mantle do not interfere with those of the adjacent rings. IThc mantle support 32 is adapted to be adjusted for the purpose of manipulation, substantially as shown in my application for Letters Patent filed June 26, 1906, Serial No. 322,890, and this mantle supporting plate is in some respects an improvement on the structure there illustrated. By thus arrangingthe parts, I secure. the further advantage of eflectively protecting the burners so that the lamp may be used out of doors or in places where there is a strong draft.

The valve casing 6 is provided with a trap chamber 40 in the lower portion thereof, to which the gas delivery pipe 3 is connected; see Figs. 9 and 10. Above this trap chamher is the valve chamber 41, which is connected to the trap chamber by means of the passage 42. The Valve 43 is a hollow valve of the lug type, and is provided with ports 46 an 47. The port 46 is adapted to be brought into registry with the port 42, as the valve is revolved.

members 27. See Fig. 1. On thevalve stem is a pin 45 adapted to engage this hingev member, and thereby limit the movement ofv The stem 44 projects between the bifurcated outer end of the hinge chamber by means of the passage Both 13o of these passages 50 and 51 are preferably connected to said gas delivery pipe; a chimprovided with valves 53 and 54, respectively, whereby they may be regulated. The passage 51 is controlled by the valve 43, it being provided with a port 47 therefor. This port 47 is so arranged that it is opened and closed on the opening or closing movement of the valve thereby flashing the pilot, the valve bein shown in the drawing artially 0 en and in position to flash the pi ot. -By t us arranging the ports, the gas is supplied to the main burners somewhat before the pilot burner is flashed, and the continued opening movement of the valve cuts off the auxiliary supply of gas to the pilot, the valve 53 for the passage 52 being adjusted to maintain a continuous flame. The pilot 55 is connected to the valve casing at the lower end of the chamber 50, and is arranged through the flange on the chamber as clearly appears in Fig. 1 of the drawing. By arranging the parts in this manner, I provide an effective tra for any sediment, or water, or other matel'ial that may be carried down with the gas, which is effectively collected before reaching the burners, and before reaching the valves, sothat it cannot clog the ports or passages thereof. I rovide the trap chamber with a plug 49, so t rat the sediment or other matter collected may be drained off. This is of par-- ticular advantage on out-of-door lamps, where there is likely to be considerable condensation within the pipes.

It is also of very great advantage to provide a tra for collecting such materials as would be llkely to clog the burner nozzles in lamps of this character where the nozzles are inverted, as very small particles, such as pieces of dirt, or rust, or the like are sufficient to clog the nozzles. By this arran ement, such materials passing down the gas delivery pipe are effectively prevented from reaching the nozzles.

To further protect the nozzle 57 from cloging, I provide an inwardly-projecting-flan c like lip 58 about the nozzle opening 59. T is forms a trap about the nozzle opening into which sediment'orthe like may be collected. The nozzle is threaded upon the nipple 56, as clearly a pears from the drawing.

I have il ustrated and described my imroved gas lamp in detail in the form preerred by me on account of its structural simplicity and economy. I am, however, aware that it is ca able of considerable variation in structural etails without departing from my invention, and I desire to be understood as claiming the same specifically, as illustrated,

as well as broadly-r Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
